When compiling the code below, gfortran emits warnings about unused
variables which are not defined by the user:

module misc_utils
implicit none

interface toString
  module procedure toString_i, toString_sp
end interface

contains

function toString_i (num)
  integer, intent(in) :: num
  character (len=30) :: toString_i

  write(toString_i,*) num
  toString_i = trim(adjustl(toString_i))
end function

function toString_sp (num)
  real, intent(in) :: num
  character (len=30) :: toString_sp

  write(toString_sp,*) num
  toString_sp = trim(adjustl(toString_sp))
end function

end module misc_utils

Interestingly, the warnings are issued for line 5, which only contains
the interface description.
